Originally, that was included in the idea hahahah! My idea was to make different cards, like:
1~5 - bronze cheap cards, just the card with some small animation, maybe
6~9 - silver more cool cards, adding a more cool animation and a silver border
10~13 - gold cards, with a super pretty border, and the critters would be moving and all that haha
But since doing those cards took a ton of time, I ended up simplifying things, just adding some cool shaders to the multiplier cards.
Thanks a lot for the feedback and for playing it :). I'll make sure to add those animations in case I develop this further!
